摘要
本文提出一种用于混沌光学系统控制自适应控制技术。此自适应控制技术以受控混沌光学系统与其动力学模型的输出差值作为反馈控制函数的宗量,由反馈控制函数的输出对混沌光学系统的系统控制参数进行调整以达到控制目的。由于该技术可消除外界因素导致的系统控制参数漂移现象对系统运转的影响,故特别适合于需要混沌光学系统运转稳定在某一具体动力学状态情形下的控制。本文将此技术应用于控制布拉格声光双稳系统的计算机仿真实验中,成功地实现了在发生较大控制参数漂移时仍使布拉格声光双稳系统,运转稳定在任一预定动力学状态上的控制目标。在研究中发现,此自适应技术也可用于使混沌光学系统运转在任意两个状态之间进行转换。
An adaptive control algorithm for controlling the chaotic optical system is presented in this paper,where the difference between the outputs of the chaotic optical system and its selfreferenced dynamical model is employed as the augument of the feedback control function in order to readjust the control parameter.The feasibility of this algorithm is demonstrated with the computer simulation of contrlling the Bragg diffraction acoustooptic bistable system (BDAOBS),where the running of the BDAOBS is persisted in successfully in the specific dynamic state against rather large perturbation of the control parameterthe pump laser intensity and switched between any two dynamic states.It is considered that this adaptive control algorithm is especially fittable for control in the case that the specific running state of the chaotic optical system is needed to persist in and switched between any two predetermined dynamic states.
